DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a system configuration diagram of a tire air pressure monitoring device according to an embodiment of the present invention. In this embodiment, the tire air pressure is a predetermined set air pressure Pse.
It is adjusted to be t. The tire air pressure monitoring device of the present embodiment is a device that monitors the tire air pressure and issues an alarm indicating an abnormality in the tire air pressure when the tire air pressure drops below a predetermined value from the set air pressure Pset.

As shown in FIG. 1, the tire pressure monitoring device of this embodiment comprises a sensor unit 10 and a monitoring unit 12. The sensor unit 10 is mounted inside the wheel, and is driven by the built-in battery 14 as a power source. As shown in FIG. 1, the sensor unit 10
Includes a tire pressure sensor 16, a transmission CPU 18, a non-volatile memory 20, and a transmission circuit 22.

The tire air pressure sensor 16 is an air pressure sensor that outputs a signal corresponding to the tire air pressure. The output signal of the tire pressure sensor 16 is supplied to the transmission CPU 18. The transmission CPU 18 detects the tire air pressure based on the output signal of the tire air pressure sensor 16 and compares the detected value (hereinafter referred to as the detected value Pm) with the reference values Pa and Pb stored in the non-volatile memory 20, The detection value Pm is supplied to the transmission circuit 22 at a frequency according to the detection value Pm. A tire identification code is stored in the non-volatile memory 20, and the tire identification code is supplied to the transmission circuit 22 together with the detection value Pm. The transmission circuit 22 detects the detection value Pm.
And a radio signal including the tire identification code are transmitted by the antenna 22.
To the monitoring unit 12.

On the other hand, the monitoring unit 12 is installed in the vehicle compartment and is driven by the battery of the vehicle as a power source. As shown in FIG. 1, the monitoring unit 12 includes a transmission / reception circuit 34, a reception CPU 36, a non-volatile memory 38, and a tire set selection switch (SW) 39. The receiving circuit 34 receives the sensor unit 10 via the receiving antenna 32.
The wireless signal transmitted from the side is received, and the detection value Pm and the tire identification code included in this signal are supplied to the reception CPU 36. The receiving CPU 36 compares the received tire identification code with the tire identification code registered and stored in advance in the non-volatile memory 38 to determine the tire at which position (left front wheel, right front wheel, left rear wheel, right rear wheel). Whether or not there is an abnormality in the tire air pressure is determined based on the received detection value Pm.

Here, the non-volatile memory 38 stores tire identification codes of a plurality of tire sets (for example, two sets). For example, as shown in FIG. 2, tire identification codes IDA1 to IDA5 of standard tires are registered at addresses # 0 to # 4 of the nonvolatile memory 38. I
DA1 is the tire identification code of the left front wheel, IDA2 is the tire identification code of the right front wheel, IDA3 is the tire identification code of the left rear wheel,
IDA4 is the tire identification code of the right rear wheel, and IDA5 is the tire identification code of the spare tire. Also, address # 5
The tire identification code IDB1 of the studless tire is # 9.
~ IDB5 is stored. IDB1 is the tire identification code of the left front wheel, IDB2 is the tire identification code of the right front wheel, IDB3
Is the tire identification code of the left rear wheel, IDB4 is the tire identification code of the right rear wheel, and IDB5 is the tire identification code of the spare tire. Which tire set registered in the non-volatile memory 38 is used for the tire identification code is instructed by the tire set selection switch 39.

If a predetermined value (for example, all zeros) is registered in the addresses # 4 and # 9 where the tire identification code of the spare tire is registered, it means that the spare tire of the tire set is not mounted. A studless tire that is used only for a short period of time may not be equipped with a spare tire. In this case, all zeros are registered in address # 9. This is because the tire identification code IDB5 of the spare tire is registered in the address # 9, and when the spare tire of the studless tire is not actually mounted, the receiving CPU 36 wirelessly transmits from the spare tire of the studless tire for a predetermined time or more. This is because it is erroneously determined that the spare tire of the studless tire is abnormal (battery exhausted) when no signal is transmitted.

As described above, since the tire identification codes of a plurality of tire sets are registered in the nonvolatile memory 38 of the monitoring unit 12, for example, standard tires and studless tires are changed every season, that is, periodically. In the case of replacement, it is not necessary to register the identification code of each tire, and tire replacement can be performed efficiently.

The monitoring unit 12 also comprises a display warning device 40. The display / warning device 40 displays a numerical value of the tire air pressure, and gives a warning when the tire air pressure is abnormal, for example, by using first to third warning lights. The receiving CPU 36 stores the predetermined first to third alarm values P1 and P in the nonvolatile memory 38.
2 and P3 (P1>P2> P3) are stored, and when the detected value Pm falls below P1, P2, and P3, the first warning light, the second warning light, and the 3 Turn on the warning light.

The first to third alarm values P1 to P3 are set to be, for example, 1.5 atm, 0.7 atm, and 0 atm based on the atmospheric pressure. Therefore, the first
An alarm (first alarm) that indicates an initial decrease in tire pressure when the warning light is lit, an alarm that indicates puncture of the tire (second alarm) when the second warning light is lit, and a third warning light is lit. As a result, an alarm (third alarm) indicating that the tire air is completely exhausted is issued.

The number of alarm values is not limited to three, and one or two alarm values or four or more alarm values may be provided. Further, instead of the first to third warning lights, for example, an alarm device for issuing an alarm by sound such as a buzzer may be provided. To register the tire identification code in the non-volatile memory 38, the registration switch provided in advance is operated to enter the registration mode, and after the registration mode is entered, for example, the left front wheel, the right front wheel, the left rear wheel, The tire identification code is registered in the order of the right rear wheel and the spare tire (the order is predetermined). Of course, the registration switch may specify the left front wheel, the right front wheel, the left rear wheel, the right rear wheel, and the spare tire for registration. Further, if it is not necessary to distinguish the left front wheel, the right front wheel, the left rear wheel, the right rear wheel, and the spare tire, registration may be performed in any order.

By the way, tire replacement (rotation)
Then, it is necessary to re-register the tire identification code registered in the non-volatile memory 38. Conventionally, the sensor unit 10 is provided by sweeping a strong magnet or the like close to the tire.
In the registration mode, the tire identification code is transmitted, and the tire identification code is received by the monitoring unit for registration, but in this case, a special instrument such as a strong magnet is required. In the present invention, the tire identification code is re-registered in the non-volatile memory 38 at the time of injecting air, thereby eliminating the need for a special device when re-registering.

FIG. 3 shows a flowchart of a routine executed by the transmission CPU 18 of the present invention. This routine is repeatedly executed at predetermined time intervals. When the routine shown in FIG. 3 is started, first, step S10 is executed. In step S10, the current tire air pressure Pm is detected based on the output signal of the tire air pressure sensor 16. In step S11 subsequent to step S10, the difference dP (= Pm- between the current tire air pressure Pm and the previous tire air pressure Pmk).
Pmk) exceeds a predetermined value dP1,
If dP ≦ dP1, the process proceeds to step S12, and dP> d
If it is P1, the process proceeds to step S24.

At step S12, it is judged if the tire air pressure Pm is below a predetermined reference value Pa (for example, Pa = P1). As a result, if Pm <Pa and the tire pressure is abnormal, then step S14 is executed. In step S14, the timer T is set to the predetermined value t.
It is determined whether it is 1 or more, and if T ≧ t1, step S1
In step 6, the tire pressure Pm and the tire identification code are transmitted to the monitoring unit 12. The predetermined value t1 is, for example, 2
It is a value corresponding to 3 seconds. Thereafter, the timer T is reset to 0 in step S18 and the process proceeds to step S22.

On the other hand, if T <t1 in step S14, the timer T is incremented by 1 in step S20 and the process proceeds to step S22. In step S22, the tire air pressure Pm detected this time is transferred to the previous tire air pressure Pmk, and this processing cycle is ended. D in step S11
If P> dP1, it is assumed that the tire air pressure is rapidly increased, that is, if air is injected into the tire, this is used as a trigger to proceed to step S24 to re-register the tire identification code in the nonvolatile memory 38. Therefore, the tire identification code read from the nonvolatile memory 20 is continuously transmitted to the monitoring unit 12 N times (several times to several tens of times). After that, this processing cycle is ended. The reason why the tire identification code is repeatedly transmitted N times in this way is to prevent reception failure in the monitoring unit 12.

As described above, since the tire identification code is registered in the non-volatile memory 38 using the air injection to the tire as a trigger, a special tool such as a magnet is required when the tire identification code is registered. do not do. The frame format of the signal for transmitting the tire air pressure Pm and the tire identification code in step S16 is shown in FIG. In the figure, a start bit for synchronization is provided at the beginning, and a tire identification code for identifying the sensor unit 10 is provided next. Next, the cord of the tire air pressure Pm is arranged.
Finally, a stop bit for synchronization is provided. On the other hand, FIG. 4B shows the frame format of the signal transmitted to re-register the tire identification code in step S24. In the figure, a start bit for synchronization is provided at the head, a tire identification code for identifying the sensor unit 10 is repeatedly arranged twice, and the tire pressure Pm is not arranged. Finally, a stop bit for synchronization is provided.

In this way, when the tire identification code is re-registered by making the signal frame format for transmitting the tire pressure Pm different from the signal frame format for transmitting the tire identification code. Even if a signal of the signal frame format of FIG. 4 (A) is transmitted from a sensor unit provided on a tire of a nearby vehicle, the tire identification code of the signal frame format of FIG. 4 (A) is erroneously reregistered. It will not be done.

A receiving antenna is provided in the vicinity of the mouthpiece for injecting air into the tire of the air injecting device, and this receiving antenna is connected to the receiving antenna 32 of the monitoring unit 12 to increase the receiving sensitivity. Further, when the monitoring unit 12 receives a signal in the signal frame format shown in FIG. 4B, the tire identification code received by the display warning device 40 may be displayed.

It is necessary to register the tire identification code in the non-volatile memory 38 when the vehicle is manufactured. Conventionally, the sensor unit 1 is provided by sweeping a strong magnet or the like close to the tire.
The tire identification code is transmitted in 0 as the registration mode, and the tire identification code is received by the monitoring unit for registration. In this case, the tire identification code is simultaneously stored in the nonvolatile memories 38 of a plurality of vehicles in the manufacturing plant. If an attempt is made to register, the signal transmitted from the sensor unit 10 of the adjacent vehicle may be received by the monitoring unit of the own vehicle, resulting in erroneous registration.

In the present invention, when the tire identification code is registered in the non-volatile memory 38, the tire identification code is entered from the bar code and registered, so that the tire identification code is registered in the non-volatile memories 38 of a plurality of vehicles at the manufacturing plant. It is possible to register at the same time. Therefore, in the sensor unit manufacturing process, the nonvolatile memory 20 of each sensor unit 10 is
The tire identification code stored in (1) is recorded on a sticker (or tag) with a bar code, and this bar code recording sticker is stored as a pair with the sensor unit 10 or its packaging.

Next, in the tire assembling step, the sensor unit 10 is installed in the tire and assembled to the wheel, and the bar code recording sticker paired with the sensor unit 10 is attached to the assembled tire. Furthermore, in the vehicle assembly process,
After assembling the tire and the monitoring unit 12 to the vehicle, as shown in FIG. 5, the barcode of the barcode recording sticker 52 attached to the tire 50 is read by the barcode reader 54.
And the read tire identification code from the bar code reader 54 through the connection cable 56.
Supply to 2. In this case, the monitoring unit 12 receives the tire identification code from the bar code reader 54 and receives CP.
An input interface 58 is provided to supply U36.

Thus, at the time of registration, the tire identification code is read by the bar code reader 54 and the connection cable 56 is obtained.
Therefore, even if the tire identification codes of a plurality of vehicles are simultaneously registered at a short distance, the tire identification codes of the sensor units 10 of adjacent vehicles are erroneously registered in the non-volatile memory 38 of the vehicle. There is no danger of

In the above embodiment, the sensor unit 10 corresponds to the transmitting unit described in the claims, the monitoring unit 12 corresponds to the receiving unit described in the claims, and the bar code reader 54 reads the code. Corresponds to the means.

[0031]

As described above, the invention according to claim 1 is
Since the tire identification code is registered in the storage section of the receiving section by injecting air into the tire as a trigger, no special equipment such as a magnet is required when performing tire rotation to register the tire identification code. .

According to the second aspect of the present invention, the tire identification code of the tire set is registered in the storage section of the receiving section by reading the tire identification code attached to the tire with the code reading means and receiving the signal through the connecting cable. Therefore, even if the tire identification codes of a plurality of vehicles are simultaneously registered at a short distance, it is possible to prevent the tire identification codes of other vehicles from being erroneously registered.
